Hi, first time pool owner. We got an 18’ round metal above ground pool. We also got the stairs that curve and are plastic that fills with water and sand. I’m trying to close my pool for the season and reading the manual for the stairs says either take out or leave in the middle of the pool. Obviously I’d rather leave in since there is no way I’ll be able to get these out on my own. However I don’t want them expanding and breaking from winter either since they nearly cost a grand. Has anyone left theirs in the pool? We live outside of Philadelphia so we get decent cold weather. We also don’t have a deck yet for the pool, future project next summer or the following summer. Thanks for advice.
